James Blish (1921-1975) was one of those rare authors who sought to fuse the imagination and ideas of science fiction with the language and power of mainstream fiction. He wasn't rare for attempting this combination, he was rare because he succeeded. His novels and short stories illuminated a bold new style of writing that helped shape the Golden Age of science fiction, and continued for more than thirty years. For the first time in more than twenty years, we're pleased to present this collection of his best short fiction. Chosen and including an introduction by his wife, Judith Blish, these masterful short stories capture the essence of James's visionary fiction. Includes the stories "Citadel of Thought, Nor Iron Bars, A Dusk of Idols" and many more.
